APPARATUS FOR VENTILATING PULPITS, 86C.

Speccaton of Letters Patent N o. 19,089, dated January 12, 1858.

To all whom t may concern:

Be it known that I, JAMES P. HERRON, of Huntsville, in the county ofLogan and State of Ohio, have invented, made, and used a new and usefulinvention, which I term the Inspiratory Aura-Duct for VentilatingPulpits and for other Purposes; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, making a part of thisspecification, in which- Figure 1, is a front view of the apparatusattached to the pulpit in the rear thereof. Fig. 2, is a verticalsectional side view of the same. Fig. 3, is a sectional view of themouth and jaw part of the apparatus.

The nature of my invention consists in attaching to and combining with apulpit, desk, 0r rostrum an apparatus whereby a supply of fresh, pureair is afforded to a speaker occupying such places, and at the sametime, admitting of medicating the pure air, to be diffused around aboutthe pulpit, for inhalation. The better however to explain the nature ofmy invention, the con struction and operation thereof are as follows.

A suitable tube or pipe being provided in any desired manner to inductwithin a building a suiiicient amount of external atmosphere, or freshoxygen. This tube or pipe similar to that represented at a, a, a, Fig.2, is connect-ed on to avertical pipe b, b, attached to the rear or backpart of the pulpit stand as in Figs. l, and 2. To the upper extremity ofsaid pipe is attached a mouth part c, c, formed with a throttle cl, andjaws e, e, f f. Within this mouth part is arranged or attached to thejaw f, j", a receptacle g, g, Figs. 2 and 3, extending across the mouthpart, right and left, from cheek to cheek h, h, Fig. l. This receptacleis of a semicylindrical shape, and does not fill up the whole spacebetween the jaws of the mout-h c, c. Suspended above this receptacle g,g, upon an axis, is a tongue-valve z', j, This tongue-valve has its endsbent or curved, the lower end conforming if desired to the concavenessof the receptacle g, g. This tongue-valve is attached by its upper endto an adjusting set screw K, K passing through the jaw f, f, and nearthe end of the jaws, toward the lips L, L2 is another adjusting setscrew m, m. To the side of one of the cheeks b, is a small orifice withtube a and stopper Fig. l.

The operation of my inspiratory auraduct is as follows, viz. Thehorizontal pipe or tube a, a, a, being beneath the floor or platform tobe occupied by the speaker or declaimer, and communicating with theoutdoor, or external atmosphere, the fresh or pure current enters thepipe 2 and passes upward in the direction of the arrows, and when thetongue-valve z', z',-j, j, is in the position indicated in Fig. 3, thecurrent continues on and out between the lips L, L2, the quant-ity orvolume being regulated` in escape, by the opening or closing of the lipsL, L2, through the intervention of the regulating set screw m, m. Whenit is desirable to counteract, and rectify the injurious tendency orinfluence of a dense, and noxious atmosphere, a medicated fluid or othervolatile agent may be deposited in the receptacle g, g, and in order toincorporate or mingle it with the passing current of air, by turning theadjusting set-screw K, K, whereby the tonguevvalve is changed inposition, as indicated by the dots 0, o, Fig. 3, and by the tongue-valvez' z' y', Fig. 2. Thus the current of passing air is deflected andpasses into the receptacle g, g, mingling with the volatile agent, whichbeing taken up by the air passes out in the direction of the bent arrowP P P, Fig. 2 and is diffused or distributed around about the speakerwho can readily inhale the medicated air, standing as he may be near tothe apparatus located as before described behind the pulpit-stand.

It is well known, that in rooms or dwellings wherein large numbers ofpersons are congregated, and where the internal atmosphere becomesvitiated, by the noxious fumes or vapors arising from bad ventilation,and where there is an absence of a due amount of oxygen, most seriousand pernicious results have ensued, to persons inhaling or taking intotheir lungs corrupted air, and it has long been a great desideratum tocounteract such deleterious influences, and various devices andcontrivances have been produced for the purpose, but the desired resultshave not been heretofore attained to the extent sought after. It isbelieved though that my medicated, inspiratory aura-duct accomplishesperfectly the object aimed at.

I-Iaving given a plain, practical eXplai nation of the nature,construction, operation, and application of my invention, -it is deemeduseless to enlarge scientifically and more elaborately upon the meritspertaining to 1ny said invention, as all Who are familiar With thenecessity of such an invention, can

readily comprehend and appreciate its.

utility.

I am Well aware that tubes, pipes and vents have been used forVentilating dwellings and other places, and such devices, I do notclaim. But

What I do claim as of my OWn invention,

and desire to secure by Letters Patent of 15 the United States, is

The manner or mode herein described, with the inspiratory aura-ductformed as shown, and constructed of the mouth and jaw parts o, 0, d, e,e, f, j", the receptacle g, g, the tongue Valve z', -j, j, incombination with the air conducting tubes and pipes, a, a, a-b, b, Z),Figs'. l, 2, 3 or in any equivalent manner substantially the same.
